Delta Optical Extreme 7x50 ED is a robust and durable binocular with exceptional optical performance. Inside the binoculars you will find BaK4 prisms and ED glass lenses with FMC anti-reflection coatings. Thanks to this combination you get an extremely bright, sharp and high‑contrast image across the entire field of view. In addition, there is no chromatic aberration and the entire system offers 90% light transmission. On top of that, the binoculars boast parameters such as 7x magnification and a 50 mm objective diameter. This allows you to comfortably observe at medium distances, even at dusk or at night.
This makes it perfectly suited for hunting as well as part of military equipment. The optics are housed in a durable metal body coated with a special rubber armour. The binoculars are not only waterproof, but also nitrogen‑filled. The lenses therefore will not fog up even with sudden changes in temperature or air humidity. The mechanical system of the binoculars withstands temperatures from -40 to +70°C.
The extreme feature set unfortunately is reflected in the overall weight of the binoculars. However, if you are looking for a well‑equipped binocular, you will accept the weight of 1340 g. Carrying is made much easier thanks to the strap with caps, or the rigid case with strap. With such a heavy unit, tripod use is also envisaged. Therefore, the manufacturer has included a tripod adapter (1/4").
